I'm a dinosaur that has seen the star fall and is waiting for the shock wave of retirement to hit but I still maintain that there is pedagogical value in teaching labs having hardcopy reference libraries. When it comes to value and utility nothing beats the Aldrich catalogue.

Statistical probabilities can be difficult to explain. But as long as the slope is greater than the noise this is statistically true: As hot as it has been this summer, it is likely that this summer will be the coolest summer that you will experience for the rest of your life

I have always had a very "lived in" office. The University decided to replace the floor and paint the walls. I have resolved to only take books and supplies out of the boxes as I actually use them and anything still in boxes come early September will be recycled or donated.

My first trip to the hospital as a grad student was from demonstrating the generation and condensation of Cl2. Someone replaced the conc HCl with conc H2SO4 in my demonstration set up and I did not notice the difference until the explosion. Adventures in manganese sub-oxides.

I regularly donated blood until 1984 when I lived and studied at Durham U during the height of the UK Mad Cow outbreak. I was forbidden to donate until early this year. It felt good to pull out my old card and donate again. Spread the news, give blood if you can @CanadasLifeline

Completed another orbit and have leveled up to my Europium year. Benign and boring, yeah sounds about right.

Used @VernierST probeware near a hilltop church to observe the eclipse. Monitored the Sun with a pinhole camera obscura. The eclipse occurred in a clear sky but less than 10 min later a cloud moved in. Temperature and illumination data clearly captured totality. Most Excellent.

Did you know David Suzuki was once a speaker at an APICS (now Science Atlantic) conference? At the 1980 Education Conference in Sackville, NB, Suzuki spoke on the ever-relevant topic of science as a tool for living in an increasingly technological world. #ThrowbackThursday

As we approach the end of semester and faculty facing piles of marking stalk the hallways I can only come to one conclusion: Collegiality is actually work avoidance.

Sometimes our job allows us get to stand up and say nice things about people you respect, admire and like. Friday I got to present @keithsgrant with the '24 Steeves Service Award. Congratulations to @isaacsoon2, @CathleneHillier and Don Moore for their awards as well. Respect.

I do not know why people are shocked by this. This could be a video of us testing to see if our S4N4 was pure back in the 80's. The pure stuff knocked the pestle out of your hand.

Can you heat your powerless house with candles? The Intro Chem students are using @VernierST temperature probes, pop can aluminum calorimeters and votive candles to find out.

Canadian concepts: Driveway Laminate: when a sequence of snowfalls, that individually are not significant enough to clear, accumulate and go through freeze/thaw cycles to form an impervious amorphous concretion anchored to the driveway. AKA: Old Man Killer. Solution? Salt.

Every time I dip into the heterocycle literature I have to read titles and abstracts like this.
What the... Even if this sentence was perfectly punctuated, with added parentheses to aid context, it would still be a terribly written headline!
